Atlantic Hurricane Outlook – August 7, 2025: Dexter Becomes Extratropical; Invest 96L Watches Intensify
Tropical Storm Dexter is nearing its transition into a post-tropical system over the North Atlantic, while a tropical wave designated Invest 96L is gaining strength and has a high potential to develop over the coming days.
Atlantic Basin Summary
Tropical Storm Dexter has sustained winds near 50 mph and is centered around 40.6°N 52.1°W. It's moving east-northeast at approximately 18 mph and is expected to become a strong extratropical low within the next several hours.
Invest 96L, a tropical wave in the eastern Atlantic, now carries a 60% chance of developing into a tropical depression or storm within seven days. It's gaining better organizational structure amidst gradually supportive conditions.
A low-pressure area offshore of the Southeast U.S. retains a 30–40% development chance over the week, but is expected to remain well off the coast and should not pose a land threat.
Key Environmental Conditions
Sea Surface Temperatures (SSTs):
Waters across the Gulf, Caribbean, and Main Development Region remain 2–4°F above average, with locations near southwest Florida reaching nearly 90°F—providing abundant energy for storm formation.Wind Shear:
Wind shear is gradually easing, especially in the central and eastern Atlantic, offering more opportunities for systems like Invest 96L to organize further.Saharan Air Layer (SAL):
Dry and dusty SAL air still suppresses convection across parts of the basin, but its influence may be waning—especially in regions where moisture is increasing.Seasonal Context:
Meteorologists note an uptick in activity as August unfolds, in line with seasonal climatology and current environmental signals including marine heat waves.
Outlook Summary
Tropical Storm Dexter is at the tail end of its life cycle, now transitioning to an extratropical system. The main attention now shifts to Invest 96L, showing increasing potential for development, and a weaker disturbance offshore of the Southeast U.S.—both deserving close monitoring as we move further into the season.
TL;DR – August 7 Snapshot
Tropical Storm Dexter is becoming extratropical and poses no land threat.
Invest 96L carries a 60% chance of development this week.
Another disturbance offshore the Southeast U.S. has 30–40% development odds but remains away from land.
Warm ocean temperatures and easing shear are creating a more favorable environment.
The active season is ramping up—stay prepared and stay tuned.
